 Keeping a pump in good working condition is essential for cost-effective and reliable operation of plants and systems. When working properly, mechanical seals are generally safe and reliable. Problems occur when the sliding faces of a mechanical seal are not adequately lubricated, resulting in a dry-running condition that ultimately causes the destruction and breakdown of the seal.
To combat the problem of dry running, EagleBurgmann has developed its DiamondFaces seal-face coating. Diamond is the hardest natural mineral known and offers excellent chemical and thermal resistance. A microcrystalline coating of 8-µm thickness on a silicon carbide seal face extends the life of the seal, reducing maintenance costs and minimizing lifecycle costs for pump users. By using mechanical seals coated with DiamondFaces, the company says the average service life of mechanical seals substantially increases. This allows pump operators to schedule preventive inspections of mechanical seals and eliminate or reduce the costs of unplanned process interruptions.
